Wi-Fi sensor networking module has 5-year battery life

San Jose, Calif.RF Monolithics Inc. has released a low-power Wi-Fi sensor networking module dubbed the WSN802G.

According to RF Monolithics, the WSN802G 802.11 b/g module is the first RFM RF module to integrate the GainSpan GS1010 SoC, a low power Wi-Fi chip solution. In addition, it enables OEMs to build low-power WLAN and sensor monitoring products for the global market.

To achieve its low power consumption and long battery life, the WSN802G combines 1 Mbit/s and 2 Mbit/s data rates, with an advanced sleep management feature that puts the module to sleep between active periods. Depending upon the frequency of active periods, a single AA Lithium cell can provide a battery life in excess of 5 years. When the module is active, its current consumption is less than 200 mA, allowing a battery to adequately power the device. Its sleep current consumption is less than 8 µA.

The WSN802G features a configurable automatic I/O reporting capability and the ability to collect sensor data directly from devices using its analog, digital and serial I/O. The WSN802G is also user programmable; therefore, developers do not need to write an application to load into the module to implement I/O functionality, or a co-processor to send appropriate commands. The WSN802G is also compatible with standard 802.11b/g Wi-Fi access points.

Pricing: With a $69 single unit price and $39 per 10,000 unit price.
